The invention relates to an opening and closing propeller system for a vertical take-off and landing aircraft, and relates to the technical field of aircrafts. The system comprises a motor, a fixed paddle, a movable paddle and a paddle opening and closing adjusting mechanism, the lower end of the fixed paddle is connected with the motor, and the upper end is connected with the movable paddle through a main bearing; matched mechanical limiting structures are arranged at the top of the fixed paddle and the bottom of the movable paddle. An opening and closing paddle adjusting mechanism is mounted in the internal hollow structures of the fixed paddle and the movable paddle and comprises an upper opening and closing adjusting block and a lower opening and closing adjusting block, and a lower positioning pin of the lower opening and closing adjusting block is matched with a limiting hole in the top of the fixed paddle; an upper positioning pin of the upper opening and closing adjusting block is matched with a limiting hole in the bottom of the movable paddle, and a rotary adjusting block arranged on the opening and closing paddle adjusting mechanism is matched with an open groove in a conical surface protruding structure arranged on the inner side of the movable paddle to limit the downward moving position of the opening and closing paddle adjusting mechanism. According to the invention, the number of lift rotor components is reduced in a hovering state, and the flight resistance is reduced and the flight performance of the aircraft is improved in a horizontal cruise state.

    本发明涉及一种用于垂直起降飞机的开合桨系统,涉及飞行器技术领域。所述系统包括:电机、定桨、动桨和开合桨调节机构,定桨下端与电机连接,上端通过主轴承连接动桨;定桨顶部与动桨底部设置相互匹配的机械限位结构;定桨和动桨内部空心结构内安装开合桨调节机构,开合桨调节机构包括上下开合调节块,下开合调节块的下定位销与定桨顶部限位孔配合;上开合调节块的上定位销与动桨底部限位孔配合,并且开合桨调节机构上设置的旋转调节块,与动桨内侧设置的锥面凸起结构上的开槽配合,限制开合桨调节机构的向下移动位置。本发明实现在悬停状态下减小升力旋翼部件的数量,并在水平巡航状态下,降低飞行阻力,提升飞行器飞行性能的效果。
